However, in the present specification, the description of an intersection in which a road should be changed may be inferred and applied to even to the case of an intersection in which a road is not required to be change (that is, an intersection in which the vehicle keeps running straight in spite of the intersection) in the same/similar manner.
In some implementations, in the present invention, a step of sensing an object located in the vicinity of the intersection is performed (S920).
The processor 870 may sense an object located in the vicinity of the intersection based on the vehicle entering within a predetermined distance from the intersection.
For example, the vicinity of the intersection may include all kinds of objects included in one area based on the intersection.
Further, the object may be understood as a concept including a specific geographical feature.
The processor 870 may sense an object located in the vicinity of the intersection using the sensing unit 820.
Here, for example, the sensing unit 820 may include all kinds of sensors capable of identifying an object such as an ultrasonic sensor, an infrared sensor, and a LiDAR sensor as well as a camera disposed to photograph the outside of the vehicle.
In some implementations, in the present invention, a step of guiding a road which the vehicle should enter from the intersection using the information related to the sensed object is performed (S930).
The processor 870 may control the display unit 830 to guide (output) a road which the vehicle must enter from the intersection using the information associated with the sensed object.
For instance, the processor 870 may determine an object (or an object to be used for guiding a change in the road from the intersection) to be used for guiding the road to which the vehicle should enter from the intersection, among the objects located in the vicinity of the intersection.
Here, the object may be determined in various ways, and the contents related thereto will be described later in more detail.
When the object to be used for guiding the road which the vehicle should enter from the intersection, the processor 870 controls the display unit 830 to guide the road which the vehicle must enter from the intersection using the information related to the object.
In some examples, guiding a road, which a vehicle should enter from an intersection, may include outputting information related to the road which the vehicle should enter from an intersection through the output unit 250.
For the sake of convenience of explanation, it is described that the road, which the vehicle should enter from an intersection, is guided or output through the display unit 830, but the related contents may include that the road, which the vehicle should enter from the intersection, is guided or output through the output unit 250 (e.g., at least one of the display module 251, the audio output module 252, or the haptic output module 253).
Hereinafter, a more specific method of guiding a road which a vehicle should enter from an intersection using information related to an object existing in the vicinity of the intersection will be described with reference to the accompanying drawings.
Referring to FIG. 10, first, in the present invention, a step of starting guiding when the vehicle reaches a point where a route guidance is required (S1001).
For instance, the processor 870 may determine whether or not the vehicle has reached the point where the route guidance is required on the basis of predetermined route information and the location information of the vehicle received through the communication unit 810.
Here, the point where the route guidance is required may include an intersection in which the road described above is required be changed. In some implementations, the point where the route guidance is required may include all the points where route guidance is required, such as a point where the road should be changed at an intersection, a point where a U-turn should be made, a point where the vehicle should enter an alley, and the like.
When the vehicle reaches a point where the route guidance is required, the processor 870 may sense whether or not a camera suitable for peripheral photography exists (S1002). In step S1002, the suitable camera may be a camera included in the sensing unit 820 of the vehicle control device.
In some implementations, the camera included in the sensing unit 820 may be an AVM camera used for an AVM (Around View Monitor) function, and may be a camera provided on the front side, rear side, and both sides of the vehicle. In some implementations, the camera included in the sensing unit 820 may be a camera of a black box provided in the vehicle.
When a suitable appropriate camera exists, the processor 870 may determine whether the camera has sufficient visibility (S1003).
Visibility of the camera may be whether or not it is possible to identify the periphery of the vehicle (For instance, within a predetermined area from the vehicle) through an image received through the camera.
In some example, the processor 870 may determine whether an external environment of the vehicle corresponds to a specific condition. For example, the external environment corresponding to a specific condition may be when the visibility of the camera is bad or not enough (e.g., less than a reference visibility value). In some cases, the external environment corresponding to a specific condition may include a dark state without ambient lighting (e.g., peripheral brightness is darker than a predetermined brightness level), a rainy state, a snowy state, and the like.
If visibility of the camera is sufficient (or the reference value or greater, or the external environment does not correspond to the specific condition), the processor 870 analyzes an image in the vicinity of a point where route guidance is required using an image received from the camera (for example, a black box camera or AVM camera) (S1004).
On the other hand, when the camera is not present in the vehicle or when the camera's visibility is not sufficient (less than the reference value) (or when the external environment of the vehicle corresponds to the specific condition), a step of receiving an image near the point using a V2X image received from another vehicle or a cloud-based database (DB) is performed (S1005).
When the camera's visibility is not sufficient (or when the external environment of the vehicle corresponds to the specific condition), the processor 870 may receive information related to an object located in the vicinity of the intersection from an external device (e.g., the Internet, another vehicle, cloud, etc.) through the communication unit 810. The object may include, for example, geographical features (buildings, objects, terrain, objects, etc.), other vehicles, and alleys.
In some implementations, the information related to the object may be information including, for example, load view information or a feature of an object.
In some implementations, the processor 870 may determine whether there is a geographical feature or a vehicle which may be used as a reference of guidance near the point where route guidance is required, based on the image received via the camera or information related to the object (S1006).
If there is a geographical feature which may be used as reference of guidance near the point, the processor 870 may analyze the geographical feature (S1007). For example, the geographical feature may include a business name, a building type, a shape, a color, a material, a location, and the like.
In some implementations, the processor 870 may perform route guidance by utilizing the feature. For example, the processor 870 may output route guidance using the geographical feature, such as "turn right at the alley of CU convenience store (business name) at 50 meters ahead" (S1008).
At this time, the processor 870 may perform voice guidance through an audio output unit, or may perform image guidance or AR guidance through the display unit 830.
The display unit 830 may include a windshield or window of the vehicle, and the AR guide may be output (performed) through the windshield or window.
On the other hand, another vehicle may exist in the vicinity of the point which may be used as a reference of guidance. For example, the other vehicle may be another vehicle which is due to enter the same road as that of the present vehicle. The processor 870 may communicate with the other vehicle through the communication unit 810 and determine whether or not the vehicle may be used as a reference of guidance based on route information of the other vehicle received from the other vehicle.
When the other vehicle that may be used as guidance exists, the processor 870 may analyze features of the other vehicle (S1009). For example, the characteristics of the other vehicle may include a vehicle type, a model name, a color, a number, a location, a movement, and the like.
In some implementations, the processor 870 may perform route guidance by utilizing the features of the other vehicle. For example, the processor 870 may perform route guidance using the characteristics of another vehicle, such as "please follow white (color) sonata (vehicle type) which turns right (movement)" (S1010).
At this time, the processor 870 may perform voice guidance through the audio output unit, or may perform image guidance or AR guidance through the display unit 830.
In some cases, when the geographical feature or another vehicle, which may be used as reference of guidance, is not detected near the point where route guidance should be provided, a step of analyzing features of a road which is shown in the display unit 830 may be performed (S1011).
The characteristics of the road may include shapes of the roads, an order of alleys, and the like.
The processor 870 may perform route guidance using the features of the road. For example, the processor 870 may output guidance information for guiding a road which the vehicle should enter by utilizing the characteristics of the road such as "Turn right at a third alley (order of alleys)" (S1012).
At this time, the processor 870 may perform voice guidance through the audio output unit, or may perform image guidance or AR guidance through the display unit 830.
When order of the alleys decreases as the vehicle runs, the processor 870 may determine whether it is possible to count the alley order (S1013).
For example, if a road to be entered is the second or more remaining alley, counting is possible, and counting may not be possible if there is no alley between the road to be entered and the current vehicle.
When counting is possible, the processor 870 may count the number of remaining alleys as the vehicle runs until the vehicle passes a point where route guidance is required (or until the vehicle enters a road which is to be changed), and output different types of guidance information (S1014).
In some implementations, the processor 870 may determine whether or not a remaining time may be counted based on a distance between the road to be entered and the current vehicle and a speed of the vehicle in step S1013.
If it is possible to count the remaining time, the processor 870 may output guidance information for counting the remaining time until the vehicle passes the point where route guidance is required.
On the other hand, if the counting is impossible, the processor 870 may determine whether the driver is asking the road again (whether the driver inquires again) (S1015). This may be determined by whether or not a command asking again is received through a microphone of the user interface apparatus 200.
In some implementations, if the driver does not ask again, the processor 870 may determine whether the driver look at a geographical feature, another vehicle, or a road, which may be used as a reference, by using the internal camera (or infrared camera) of the sensing unit 820 (S1016).
When the driver looks at the geographical feature, the other vehicle, or the road which is displayed, the processor 870 may determine whether a correct turn signal is turned on (whether or not the left winker has been turned on in the case of left turn), and whether or not the vehicle has been decelerated (S1017).
In some examples, the processor 870 may terminate the guidance if the vehicle is decelerated or a correct turn signal is turned on. On the other hand, if the driver inquires the road again, if the driver does not look at the geographical feature, the other vehicle, or the road which is displayed, as a reference of guidance, if the incorrect turn signal is not turned on, or if the vehicle has not been decelerated, the process may be returned to step S1006.
The above description will be more clearly understood with reference to FIGS. 11 to 14.
First, the processor 870 may sense (determine) through the communication unit 810 that the vehicle enters an area within a predetermined distance from an intersection (or a point where route guidance is required) at which a road must be changed, while the vehicle is running along the predetermined route information.
The processor 870 may sense an object located in the vicinity of the intersection through the sensing unit 820 based on the entry.
For instance, when the vehicle enters an area within the predetermined distance from the intersection, the processor 870 may sense objects existing within a predetermined area based on the intersection.
In some implementations, the processor 870 may control the display unit 830 (or output unit) to guide the road the vehicle must enter from the intersection using use the information associated with the sensed object.
The information related to the object may include characteristics of the object, an image captured via the camera, or information related to an object received through the communication unit.
For instance, the processor 870 may output guidance information to the display unit 830 using an object which satisfies a preset condition among the sensed objects.
The object satisfying the preset condition may include at least one of an object existing between a road on which the vehicle is currently running and a road to be entered at the intersection, a type of a road which is displayed based on a position of a preceding vehicle or a current vehicle scheduled to run on the road to be entered.
In some implementations, the object which satisfies the preset condition may include at least one of the above-described geographical feature, the other vehicle, or the road which is displayed.
Referring to FIG. 11, the display unit 830 may output preset route information 1110 on the map information 1100.
At this time, a graphic object 1112 indicating the location of the current vehicle and an intersection 1114 indicating a road change may be displayed on the route information 1110.
When the vehicle enters an area within a predetermined distance from the intersection, the processor 870 may sense objects existing within a predetermined area on the basis of the intersection through the sensing unit 820, and determine an object satisfying a preset condition among the sensed objects.
For example, as shown in FIG. 11, the object satisfying the preset condition may be an object 1120 (for example, a specific building, a shop, a sign, a structure, etc.) existing between the road on which the vehicle is currently running and a road to be entered at an intersection.
The processor 870 may control the camera of the sensing unit 820 to photograph an object satisfying the preset condition. The camera may be arranged to photograph the outside of the vehicle. An image 1130 received through the camera may include an image corresponding to the object 1120 satisfying the preset condition.
The processor 870 may control the camera to photograph the image 1130 including the object based on the entry of the vehicle within a predetermined distance from the intersection. In some implementations, the processor 870 may output the image 113 captured to include the object to the display unit 830.
The processor 870 may display the image 1130 obtained by capturing the object 1120 satisfying the preset condition on the display unit 830 based on the vehicle entering the intersection within a predetermined distance (or entering the intersection) from the intersection.
In some implementations, the processor 870 may output turn-by-turn (TBT) information 1140 for guiding a road which the vehicle should enter from the intersection on the display unit 830 together with the image 1130.
The turn-by-turn information may include information (e.g., the arrow) indicating a distance remaining to the road to be entered and a direction to which the vehicle should enter.
As illustrated in FIG. 11, the processor 870 may output the road which the vehicle should enter from the intersection by a voice using the information (for example, characteristic information of the object) related to the object that satisfies the preset condition.
In some cases, the processor 870 may output AR information to be overlapped on an object satisfying the preset condition on a windshield or window included in the display unit 830, or output a graphic carpet to identify the road to be entered.
For example, the processor 870 may output the AR graphic object to a position where the AR graphic object is overlapped on the object satisfying the preset condition on the windshield or window so that the object is highlighted when the driver views the object satisfying the preset condition, or apply a graphic effect to be overlapped on the object satisfying the preset condition.
In some examples, the processor 870 may sense the driver's gaze using a sensing unit (e.g., an internal camera provided to photograph the inside of the vehicle, an infrared camera or DSM system).
The processor 870 may overlap the AR graphic object on the object and output the same on the windshield or window so as to be highlighted when the driver views the object on the basis of the object satisfying the preset condition and the line of the sight of the driver, or apply a graphic effect.
The position to which the AR graphic object is output or the position at which the graphic effect is applied may be varied based on a relative position of the driver and the object being changed as the vehicle is traveling.
In some implementations, the processor 870 may output the image 1130 (or a preview image) captured through the camera on the windshield or the window so that the image 1130 may be output to a position corresponding to the object satisfying the preset condition.
Referring to FIG. 12, the processor 870 may determine a preceding vehicle 1200 which enters the same road from an intersection through the communication unit 810, based on entry of the vehicle within a predetermined distance from the intersection.
For instance, the processor 870 may connect V2V communication with at least one other vehicle through the communication unit 810. The at least one other vehicle may include another vehicle existing within a predetermined distance based on the present vehicle.
The processor 870 may receive route information set in the other vehicle from the other vehicle. In some implementations, the processor 870 may compare the route information set in the other vehicle with the route information preset in the current vehicle and determine whether the roads to be entered at the intersection are the same.
The processor 870 may determine the other vehicle to enter the same road from the intersection as a preceding vehicle which enters the same road from the intersection.
As illustrated in FIG. 12, when the preceding vehicle 1200 entering the same road at the intersection is determined, the processor 870 may output guidance information 1220 indicating that the driver should follow the preceding vehicle on the display unit 830 (or audio output unit).
When the preceding vehicle is determined, the processor 870 may capture an image 1210 to include the preceding vehicle through the camera of the sensing unit 820, and output the image 1210 to the display unit 830 (or the windshield and window).
In some implementations, the processor 870 may capture an image received through the camera arranged to photograph the outside included in the sensing unit 820, based on the entry of the vehicle within a certain distance from the intersection.
The processor 870 may guide a road which the vehicle should enter from the intersection using at least one road identified in the image.
The at least one identified road may include the road as described above.
As shown in FIG. 13, when the vehicle enters area within a predetermined distance from the intersection where the vehicle must change roads, the processor 870 may determine at least one road identified in the image based on the image received through the camera.
If at least one road exists between the roads which the vehicle should enter from the current position of the vehicle, the processor 870 may determine the at least one road.
As shown in (a) of FIG. 13, the processor 870 may guide the road which the vehicle must enter using the at least one road. For example, the processor 870 may output guidance information 1320 indicating the road which the vehicle should enter using the at least one road through the display unit 830 (or the audio output unit or the windshield/window).
In some implementations, when at least one road exists between the roads to be entered, the processor 870 may count a road which the vehicle should pass by or may output information of counting a remaining time.
Also, as shown in (b) of FIG. 13, the processor 870 may output a graphic carpet 1340 indicating the road to be entered using the AR information on the display unit 830 (for example, a windshield of the vehicle).
If an obstacle 1330 (e.g., another vehicle) exists in the vicinity of the road to be entered through the sensing unit 820, the processor 870 may output a graphic object for warning the obstacle 1330 on the display unit 830.
In some implementations, the processor 870 may output the graphic carpet 1340 so that the vehicle may travel by avoiding the obstacle 1330.
After the guidance information is output, the processor 870 outputs the guidance information again based on at least one of whether the driver's request for re-output (or a user command to ask again) is received, whether or not the driver looks at the object used in the guidance information, whether or not the operation of the vehicle satisfying the preset condition is performed. The driver may look at the object to recognize the object.
When the driver's request for re-output is received, when the driver does not look at the object, or when the operation of the vehicle satisfying the preset condition is not performed, the processor 870 outputs the guidance information again.
When there is no request for re-output from the driver, when the driver looks at the object, or when the operation of the vehicle satisfying the preset conditions (for example, a right turn indicator is turned on when the vehicle is to turn right) is performed, the processor 870 terminates the guidance without reoutputting the guidance information.
Further, when it is detected that the vehicle has entered the road which the vehicle must enter from the intersection, the processor 870 may terminate the guidance.
In some implementations, the processor 870 may determine whether an external environment of the vehicle sensed through the sensing unit 820 corresponds to a specific condition
For example, the processor 870 may determine that the external environment of the vehicle corresponds to the specific condition, when brightness is lower than reference brightness or when camera visibility is lower than a reference value due to weather of rain/snow or an object such as tree/utility pole, etc.
For example, as shown in (a) of FIG. 14, when the external environment of the vehicle corresponds to the specific condition (for example, brightness is lower than the reference brightness), the processor 870 may receive information related to an object located in the vicinity of the intersection (predetermined area based on the intersection) through the communication unit 810.
Receiving information related to an object through the communication unit 810 may include receiving information related to the object from a communicatable device, such as an Internet resource, another vehicle, or an external server (or infrastructure) installed at the intersection.
The information related to the object may include a road view image existing in the Internet resource, an image captured through a CCTV installed at the intersection, signboard information, an image captured by another vehicle, and an image stored in a cloud database.
When the vehicle enters an area within a predetermined distance from the intersection at which the vehicle should change roads, the processor 870 may request information from the communicatable device about the object existing in the vicinity of the intersection and receive information related to the object from the communicatable device.
As described above, the display unit 830 may include a windshield or a window of the vehicle.
As shown in (b) of FIG. 14, when the external environment of the vehicle corresponds to the specific condition, the processor 870 may display information 1400a related to the object received through the communication unit 810 on the windshield or window. That is, it may be understood that the processor 870 displays the information 1400a related to the object as AR information on a windshield or window.
For example, the information 1400a related to the object received through the communication unit 810 may include a previously captured image of an object existing at the intersection or characteristic information of the object.
As illustrated in (b) of FIG. 14, the processor 870 may output the information 1400b related to the object on a display unit (e.g., CID, display, etc.) provided in the vehicle.
In some examples, the processor 870 may output guidance information for guiding the road to be entered through the display unit 830 or the audio output unit by using the information related to the object received through the communication unit 810.
In some examples, the processor 870 may output a first image captured by the camera of the vehicle and a second image received from the external device in different manners.
For example, when the processor 870 outputs the first image and the second image as AR information on the display unit 830 (for example, the windshield), the processor 870 may output the first image according to a first scheme and the second image according to a second scheme different from the first scheme.
The first and second schemes may be one of various schemes for outputting an image. For example, the first scheme may be a scheme of highlighting the image, and the second scheme may be a scheme of varying transparency of the image.
The contents described above with reference to FIG. 14 may be inferred and applied in the same/similar manner even when the camera is not provided in the vehicle.
Through such a configuration, the present invention may provide a user interface that provide route guidance to the driver more intuitively by utilizing peripheral objects at a point where route guidance is required (or an intersection where a road should be changed).
On the other hand, the vehicle control device of the present invention may autonomously run the vehicle in an autonomous driving mode. At this time, the present invention may provide a vehicle control method capable of controlling a vehicle by utilizing an object existing in the vicinity of the intersection at the intersection where a road may be changed.
Hereinafter, a method of controlling a vehicle by utilizing an object in an autonomous driving mode will be described in more detail with reference to the accompanying drawings.
FIG. 15 is a flow chart illustrating an example control method in detail according to another implementation of the present invention, and FIGS. 16, 17, 18, and 19 are conceptual diagrams illustrating the example control method illustrated in FIG. 15.
The processor 870 may receive a user command including a term corresponding to an object existing in the vicinity of the intersection (or existing within a certain area based on the intersection) in a state that a driving mode of the vehicle is the autonomous driving mode.
The user command may be received through a voice input module 211 or via a microphone of a mobile terminal connected for communication through the communication unit 810.
The term corresponding to the object may include, for example, a name of the object, a feature (shape/color/vehicle type/position/motion, etc.) of the object.
In a state that the driving mode of the vehicle is the autonomous driving mode, the processor 870 may control the vehicle to correspond to the user command based on reception of the user command including the term corresponding to the object.
Here, controlling the vehicle may include autonomously driving the vehicle to correspond to the user command.
For example, when a user command including a term corresponding to the object is received, the processor 870 may photograph the object through the camera and output the photographed image on the display unit 830 (or the windshield/window.
In some implementations, the processor 870 may sense an external environment of the vehicle through the sensing unit 820 based on reception of the user command.
When the external environment is sensed as a specific condition, the processor 870 may receive information related to the object through the communication unit 810.
For example, the processor 870 may determine that the external environment of the vehicle corresponds to the specific condition, for example, when the brightness is lower than the reference brightness or when camera visibility is lower than the reference value due to weather of rain/snow or an object such as tree/utility pole.
Receiving information related to an object through the communication unit 810 may include receiving information related to the object from a communicatable device, such as an Internet resource, another vehicle, or an external server (or infrastructure) installed at the intersection.
The information related to the object may include a road view image existing in the Internet resource, an image captured through a CCTV installed at the intersection, signboard information, an image captured by another vehicle, and an image stored in a cloud database.
When the vehicle enters an area within a predetermined distance from the intersection at which the vehicle should change roads, the processor 870 may request information from the communicatable device about the object existing in the vicinity of the intersection and receive information related to the object from the communicatable device.
In some implementations, the processor 870 may display (or output) the received information related to the object through the display unit 830 (or the audio output unit).
In the present invention, information related to the object may output to inform the driver that the user command has been correctly recognized.
More various implementations will be described with reference to FIGS. 15 to 19.
First, referring to FIG. 15, in the present invention, when the driver wants another operation mode (or wants to change a road during driving or change a driving state (driving mode) of the vehicle) during autonomous driving, the driver may start a command. Here, the command may be, for example, a voice command (S1501).
For instance, the processor 870 may receive a user command when the driver wants another operation mode (or wants to change a driving road or change a driving state (driving mode) of the vehicle) during autonomous driving.
At this time, the user command may include a term corresponding to an object existing outside the vehicle (for example, an object existing in the vicinity of the intersection).
The object may include a geographical feature, another vehicle, or a road which is displayed, as described above.
For example, the processor 870 may receive a driving command using a nearby geographical feature (S1502). That is, the processor 870 may receive a user command (e.g., "Please stop (vehicle operation) in front of a CU convenience store (geographical feature) on the right for a while) that includes terms corresponding to the nearby geographical feature.
In some implementations, the processor 870 may analyze the geographical feature of included in the user command and the vehicle motion (S1503).
Here, the geographical feature may include a business name, a building type, a shape, a color, a material, and the like.
In some examples, the processor 870 may sense the driver's gaze or gesture through the sensing unit 820 (e.g., a camera or DSM (Driver Status Monitoring) system configured to photograph the inside of the vehicle).
The processor 870 may receive a driving command with respect to another nearby vehicle (S1504). For example, the processor 870 may receive a user command (e.g., "Let's go ahead of the white sonata" that indicate another vehicle and a vehicle operation with respect to the vehicle) which includes terms corresponding to the nearby vehicle.
In some implementations, the processor 870 may analyze characteristics of the other vehicle included in the user command and the operation of the vehicle (S1505). The characteristics of the other vehicle may include, for example, a vehicle type, a model name, a color, a number, a position, a motion, and the like.
The processor 870 may also sense the driver's eyes or gesture through the sensing unit 820 (e.g., a camera or DSM (Driver Status Monitoring) system configured to photograph the inside of the vehicle).
As another example, the processor 870 may receive a driving command using a road which is displayed (S1506). That is, the processor 870 may receive a user command (e.g., "Let's go right (drive) at the third alley (road which is displayed)" including terms corresponding to the road.
In some implementations, the processor 870 may analyze the characteristics of the road which is displayed included in the user command and the vehicle operation.
The processor 870 may also sense the driver's eyes or gesture through the sensing unit 820 (e.g., a camera or DSM (Driver Status Monitoring) system configured to photograph the inside of the vehicle).
In some implementations, the processor 870 may determine whether or not a camera formed to photograph the outside (the periphery) of the vehicle exists based on reception of a user command including the term corresponding to the object (geographical feature, other vehicles, a road which is displayed, etc.) existing outside of the vehicle (S1508).
If the camera exists, the processor 870 may determine whether visibility of the camera is higher than a reference value (S1509). Visibility of the camera may be expressed as a predetermined numerical value.
Whether or not visibility of the camera is higher than the reference value may correspond to whether an external environment of the vehicle does not correspond to a specific condition.
For example, the processor 870 may determine whether the external environment of the vehicle corresponds to the specific condition. For example, a state that the external environment corresponds to a specific condition may include a state where visibility of the camera is poor or not enough (e.g., less than a reference visibility value), a dark state without ambient light in which ambient brightness is less than predetermined brightness, a rainy state, a snowy state, and the like.
When visibility of the camera is sufficient (e.g., equal to or greater than the reference value or when the external environment does not correspond to the specific condition), the processor 870 analyzes the image in the vicinity of a point where route guidance is required based on the image received by the camera (for example, a black box camera or AVM camera) (S1510).
On the other hand, when the camera does not exist in the vehicle or the visibility of the camera is insufficient (less than the reference value) (or the external environment of the vehicle corresponds to the specific condition), the processor 870 may receive the image in the vicinity of the point using a V2X image received from an Internet resource (e.g., a road view) through the communication unit 810 or another vehicle or a cloud-based database (DB) (S1511).
The processor 870 may specify (determine) an object included in the user command by comparing and analyzing the image received through the camera or the image received through the communication unit 810 and the user command (S1512).
If the object is not specified, the processor 870 may output information indicating that the object included in the user command cannot be specified (S1511).
On the other hand, if the object is specified, the processor 870 may repeat the user command so that the term corresponding to the object may be included.
For example, when the object is a geographical feature, the processor 870 may output guidance information such as "Stop in front of CU convenience store (object) on the right 50 meters ahead" and if the object is another vehicle, the processor 870 may output guidance information such as "Go ahead of white Sonata, 10 meters ahead", and if the object is a road, the processor 870 may output guidance information such as "turn right at a third alley", through the audio output unit (S1514, S1515, and S1516).
In some implementations, the processor 870 may output AR information to overlap on the specified object on the windshield or the window included in the display unit 830, or may output a graphic carpet to identify the road to be entered.
Further, the processor 870 may output the AR graphic object at a position where the AR graphic object is overlapped on the specified object on the windshield or window so as to be highlighted when the driver views the specified object, or may apply graphic effects to overlap the specified object.
The processor 870 may output the AR graphic object to be overlapped on the object on the windshield or window so as to be highlighted when the driver views the object based on the specified object and the driver's eyes, or apply the graphic effect.
The position at which the AR graphic object is output or the position at which the graphic effect is applied may be varied based on a relative position of the driver and the object being changed as the vehicle is driven.
In some implementations, the processor 870 may output the image 1130 (or the preview image) photographing the specified object through the camera to the wind shield or the window so as to be output to a position corresponding to the specified object.
When the object included in the user command is specified, the processor 870 may capture the image including the specified object through the camera, and output the captured image to the display unit 830, or display the image as AR information on the windshield or window.
Since the processor 870 repeats the user command, the driver may determine whether the vehicle control device correctly understands the user command (S1517).
When a user control command indicating that the vehicle control device properly understands the user command is received, the processor 870 may change the driving mode to correspond to the vehicle operation included in the user command (or control the vehicle)
On the other hand, if a user control command indicating that the user command is not correctly understood by the vehicle control device is received, the processor 870 may output guidance information indicating the user command should be input again or may return to step S1501.
If a driving route is changed as the driving mode is changed, the processor 870 may reset (or change) the preset route information by reflecting the changed driving route. That is, the processor 870 may change the route information in the navigation when the route is changed (S1519).
As shown in FIG. 16, when an object (e.g., geographical feature) 1600 included in a user command is specified, the processor 870 may output an image (or preview image including the specific object) captured to include the specified object on the display unit 830.
The processor 870 may output guidance information 1620 corresponding to the user command through the audio output unit using the specified object.
The processor 870 may also apply a highlight graphic effect on the windshield or window so that the specified object is highlighted.
As shown in FIG. 17, when an object (e.g., another vehicle) 1700 included in a user command is specified, the processor 870 may output the image (or preview image including the specified object) 1710 captured to include the specified object on the display unit 830.
In some implementations, the processor 870 may output guidance information 1720 corresponding to the user command through the audio output unit using the specified object.
The processor 870 may also apply a highlight graphic effect on the windshield or window so that the specified object is highlighted.
As shown in (a) of FIG. 18, when an object (for example, a road which is displayed) included in a user command is specified, the processor 870 may output an image (or preview image including a specified object) captured to include the specified object on the display unit 830.
In some implementations, the processor 870 may output a graphic carpet 1800 which guides to the road which is displayed, in the form of AR on the windshield 1300 (or window).
Further, the processor 870 may output guidance information 1810 corresponding to the user command through the audio output unit using the specified object.
As shown in (b) of FIG. 18, when an obstacle 1820 (e.g., another vehicle) near the object (for example, a road which is displayed) included in the user command is sensed by the sensing unit 820, the processor 870 may output the graphic carpet 1830 formed to avoid the obstacle 1820 in the AR format on the windshield 1300 (or window).
As illustrated in (a) of FIG. 19A, the processor 870 may sense whether the external environment of the vehicle corresponds to the specific condition through the sensing unit 820 (or that visibility of the camera is less than the reference value).
In this case, the processor may receive information related to the object included in the user command through the communication unit 810 using the V2X image or the cloud-based database (DB) received from the Internet resource (e.g., a road view) or another vehicle.
As illustrated in (b) of FIG. 19, the processor 870 may output information corresponding to the object included in the user command (for example, images 1900 and 1910 which have captured the object) to the display unit 830 (or the windshield 1300).
In some implementations, the processor 870 may output guidance information 1810 corresponding to the user command through the audio output unit using the object.
Through this configuration, the present invention may provide an optimized user interface capable of more accurately controlling a vehicle which is autonomously driven by a voice by using an object existing outside (in the vicinity) of the vehicle and capable of feeding back whether voice control is properly performed.
Outputting an image in AR format on the windshield or window, as described herein may include highlighting (or applying a graphic effect) to overlap an object on the windshield or window.
Implementations of the present invention may have one or more of the following effects.
First, the present invention may provide a user interface capable of performing more intuitive road guidance by performing road guidance using an object existing in the vicinity of an intersection when the vehicle enters the intersection where a road should be changed.
Second, the present invention may provide the vehicle control device and the method for controlling a vehicle capable of performing road guidance by using an object near an intersection photographed in real time or utilizing an object near the intersection received from an external server according to whether visibility of the camera is sufficient.
Third, the present invention may provide the vehicle control method capable of controlling a vehicle by utilizing an object existing in the vicinity of an intersection while the vehicle is running in the autonomous driving mode.
The effects of the present invention are not limited to the effects mentioned above, and other effects not mentioned may be clearly understood by those skilled in the art from the description of the claims.
